ATOM IZER.

SPECIFICATION forming part of Letters Patent No. 483,435, datedSeptember 2'?, 1892.

Application filed December 12, 1891. Serial No. 414,790. (No model.)

" `.To a/ZZ whom t may concern:

Be it known that I, HARLEY M. DUNLAP, of

i Battle Creek, in the county of Calhoun and State of Michigan, haveinvented a new and y Improved Atomizer, of which the following is afull, clear, and exact description.

i i My invention relates to improvements in that class of atomizers inwhich the spray is produced within a bottle and forced out so as to beinhaled by a patient.

The object of my invention is to produce a simple atomizer which isdurable and comi atomizer the construction of which will be hereinafterdescribed and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

i in which similar figures of reference indicate i corresponding partsin all the vlews.

Figure 1 is a broken sectional View showing the detailed construction ofthe apparatus. Fig. 2 is a broken inverted plan of the cured to thebottle.

atomizer-head and the cap by which it is se- Fig. 3 is a detailperspective view of theinhaler-mask, and Fig. l is a broken detail Viewof the spraying-tube.

The bottle is of an essentially-globular shape, this shape being givenit in order that i of solution.

the bottle may be very strong, and also to enable it to be used with avery small quantity The bottle has a broad base 11, upon which it mayrest firmly, and in the bottom of the bottle is a depression 12, intowhich the spraying-tube may be thrust, and

an extremely-small quantity of solution will, by settling in thisdepression, enable the atomizer to be successfully worked.

The neck 13 ofthe bottle 10 is screwi threaded upon the outside, andupon this a cap 14 is secured, the cap being adapted to hold in placethe head 15, which is preferably of hard rubber1 and which has a iiange16 extending between the top of the cap and the top of the bottle, agasket 16a being inserted between the iiange and the bott-le, so as toproduce an air-tight joint. The head projects well above the top of thecap 14, and it is provided with three ports opening from the bottomthrough the sides, the port 17 being adapted to connect with thesprayingtube, and being adapted, also, to connect with a nipple 18,which projects from one side of the head and connects by means of arubber tube 19 with the usual air-bulb 20, having a common form ofsuction-valve 21 at its outer end, so that by repeated compressions thebulb may be made to force a continuous supply of air into the bottle.The port 22 of the head opens directly into the bottle and also connectswith a nipple 23, which is screwed into the port and extends in anearly-horizontal position from the head, the nipple being closed by acork 24; but when the atomizer is to be used for general purposes thecork is removed, and the nipple 23 may be connected with a reservoir ofcompressed air or other gas, which will thus iiow into the bottle andmay be expelled through the outlet-port 25, which port also leads fromthe bottom of the head through one side thereof, and an outlet-nipple25a is screwed into this port and connects with a flexible tube 26, theouter end of which fits on the hollow stem 27 of the mask 28. The mask28 is of an essentially cup shape and is provided on one side with aV-shaped slot 29, which enables it to be placed over the mouth and nose,the slot fitting nicely upon the nose or beneath the nose, as desired.Near the outer edge of the mask is a cushion 30, which is preferablyhollow, and which enables the mask to t tightly upon the face of apatient without hurting him.

The spraying-tube is made in two parts 3l 32, the upper part 3l beingscrew-threaded at its upper end, as shown at 33 in Fig. 4, so that itmay be screwed into the port 17. The tube is long enough so that itslower end will almost touch the bottom of the bottle, and the lower part32 is provided near its upper end with a side opening 34, through whichair may be forced. The parts are connected by a hollow coupling 35,having a nipple 36 at one end, which screws into the part 3l of thespraying-tube, and at the other end a sub- Stantially-siiiiilar nipple37, which screws into the lower member of the spraying-tube, and thelower nipple of the coupling is flattened on one side, as shown at 38,and is provided with a side opening 39, which registers With the opening34 of the spraying-tube.

When the instrument is operated and air forced down the spraying-tube,the current of air which passes out through the openings 39 and 34 sucksup the liquid through the lower portion 32 of the tube and ejects thesame forcibly against the side of the bottle, thus producing a very finespray, which may be readily inhaled by means of the outletpipe and mask.

By placing the stopper 24 in the inlet pipe or nipple 23 and thenworking the apparatus in the manner described air may be forced into themiddle ear and accessory cavities connecting with the nasal passages. Ifdesired, the mask may be dispensed with and an ordinarymouthpiece ornasal tube be connected with the outlet-nipple.

The head l5, the Various nipples opening from the head, thespraying-tube 31 32, and the coupling 35 are all made of hard rubber,which will not corrode and which permits the use of oils in the atomizerWithout injury to it.

IIaving thus described my invention I claim as new and desire to secureby Letters Patent- 2. In an atomizer, the two-part spraying` tube havinga side opening in the lower member and a hollow coupling connecting thetwo members, said coupling having a side opening to register with theside opening in the tube, substantially as described.
